Hey all. I have a 4 year old son who s allergic to milk, grass, outdoor fungi and has asthma. He has had allergy testing done but he was only tested for some general trees,grasses,foods,and fungus. He gets random rashes and the past 3 days in a row has had a new rash come up each day. They have all been ichy and raised which i am pretty sure is contact dermatitus. The first day he layed a playpin changing pad, (being silly) he of course could only get the top of his body on it. Shortly after his stomach and back broke out. The next day we were at the park and he was sitting on some synthetic wood chips (these are made of rubber, old tires and such) and just his legs broke out. Today his whole body broke out after playing in mcdonalds play place. The changing pad he played on is made of 60% Polyester Fiber and 40% Polyurethane Foam. I dont know about the other stuff. Anyone have any ideas? Oh and the rashes have come up very shortly after contact and go away very easily with allergy meds, but are very itchy.
